On the third anniversary of the shooting that killed 20 first-grade students and six educators, Caira sent an email to parents at the Warren Elementary School in Ashland. It was a message from his heart.

It read in part, "My wish for all of you today is that you spend a little extra time with your children ... Take a moment to remember that they will only be six once. Stop and be a kid with them."

Caira encouraged parents to leave work early and let their children set the rules of the house for one night.

"Create a fort with your blankets and build a gigantic Lego city," he wrote. Caira reminded parents to tuck their children into bed, kiss them and hug them a little longer.
